18 Questions
What happens to soil porosity and infiltration as bulk density increases?
Porosity and infiltration both decrease
How does organic matter affect infiltration?
Organic matter increases infiltration
How do the chemical properties of the soil affect infiltration?
Both b and c
How does soil water content affect the infiltration rate?
Higher water content leads to lower infiltration rates
How do the water retention characteristics of clay and sandy soils differ?
Clay soils drain water more slowly than sandy soils, even though they have smaller pore spaces
How does the water retention characteristic of a soil affect infiltration in successive rain events?
In successive rain events, clay soils may remain saturated between storms, producing more runoff
